Comment on “The Chongón/Colonche orocline transrotational bending and the coeval opening of the Progreso basin in southwestern Ecuador” by Alemán et al

•Lack of evidence to support a counterclockwise rotation of the Piñon block and the coeval opening of the Progreso Basin.•Forearc basin controlled by the complex interplay of oblique subduction, rise of an outer forearc high, and tectonic escape.•Post-accretion strain partitioning across an outer wedge with a varying trench-parallel oriented deformation.
